What is the delta in fingerprint analysis?

In fingerprint analysis, a delta is characterized by the point of divergence of ridge patterns. It marks the area where two ridges form a fork, with one ridge leading off in one direction while the two ridges diverge from a common point. Specifically, the delta serves as a crucial reference point for classifying fingerprints into different types based on their patterns (loops, whorls, or arches).

This point of divergence is vital for identifying and comparing fingerprint patterns, as it helps forensic analysts determine the overall structure and classification of the print. In this context, recognizing the delta allows for a more organized and systematic approach to fingerprint analysis, which is essential in forensic investigations. The significance of the delta in this capacity underlines its role in the classification and identification processes in latent print analysis.
